DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 1. Configuration ofVehicle Utilization Support System

With reference to FIG. 1 to FIG. 4, a configuration of a vehicleutilization support system 1 in the present embodiment will bedescribed. The vehicle utilization support system 1 gives supportregarding selection of a moving route when a user Pu of a rental vehicle100 provided by rental or car sharing or the like moves using the rentalvehicle 100.

The vehicle utilization support system 1 communicates with an in-vehicledevice 110 loaded on the rental vehicle 100, a user terminal 120 carriedby the user Pu of the rental vehicle 100, and a vehicle managementserver 200 that manages use of the rental vehicle 100, through acommunication network 500. The in-vehicle device 110 corresponds to acommunication terminal used by the user of the rental vehicle in thepresent invention.

FIG. 1 shows a case where three moving routes that are a first movingroute Rt1, a second moving route Rt2 and a third moving route Rt3 areextracted as the moving route from a first spot Mp1 which is a currentposition of the rental vehicle 100 to a second spot Mp2 which is ascheduled return spot of the rental vehicle 100 set upon a reservation,by the vehicle utilization support system 1.

The first moving route Rt1 is the moving route of traveling through ageneral road which does not require a travel charge from the first spotMp1 to the second spot Mp2. The second moving route Rt2 is the movingroute of traveling by utilizing a highway 300 which requires the travelcharge from the first spot Mp1 to the second spot Mp2. The third movingroute Rt3 is a combined moving route for which movement by the rentalvehicle 100 and movement by a train 420 (corresponding to publictransportation in the present invention) are combined.

A moving section Rt31 by the rental vehicle 100 is from the first spotMp1 to a third spot Mp3 of the third moving route Rt3, and the user Pureturns the rental vehicle 100 at the third spot Mp3. A moving sectionRt32 by the train 420 is from the third spot Mp3 to the second spot Mp2.

Next, referring to FIG. 2, in a storage device (not shown) of thevehicle management server 200, vehicle management information 201 isstored. As shown in FIG. 3, in the vehicle management information 201,for the individual rental vehicle registered in the vehicle managementserver 200, a vehicle ID (identification) indicated by a sign 201 a, avehicle reservation No. indicated by a sign 201 b, a vehicle reservationperiod (a usable period of the vehicle) indicated by a sign 201 c, avehicle rental spot indicated by a sign 201 d, a vehicle return spotindicated by a sign 201 e, and a user ID indicated by a sign 201 f orthe like are recorded. When a rental vehicle is not returned within thevehicle reservation period, an excess charge is incurred.

The vehicle utilization support system 1 is a computer system configuredby a CPU (Central Processing Unit) 10, a memory 30, and a communicationpart 40 or the like. In the memory 30, a control program 31 of thevehicle utilization support system 1, user management information 32,map information 33, public transportation information 34, and movingroute information 35 or the like are stored. In the user managementinformation 32, a profile of the user registered to receive a supportservice provided by the vehicle utilization support system 1, and a userID issued to the user or the like are recorded. In the map information33, road information including information of toll roads such ashighways is recorded. In the public transportation information 34,information of operating routes, charges and required time or the likeof the public transportation such as railroads and buses is recorded.

In the moving route information 35, as shown in FIG. 4, for theindividual moving routes extracted by a moving route extraction part 12to be described later, information of a moving route No. indicated by asign 35 a, the travel charge indicated by a sign 35 b, predicatedrequired time indicated by a sign 35 c, a predicated excess chargeindicated by a sign 35 d, a predicted energy charge indicated by a sign35 e, presence/absence of a rental vehicle intermediate return spotindicated by a sign 35 f, a public transportation charge indicated by asign 35 g, and a total charge 35 h or the like is recorded. In FIG. 4,the information of the first moving route Rt1, the second moving routeRt2, and the third moving route Rt3 shown in FIG. 1 is illustrated.

By reading and executing the control program 31 stored in the memory 30,the CPU 10 functions as a user management part 11, the moving routeextraction part 12, a travel charge calculation part 13, a predictedmoving time calculation part 14, a predicted excess charge calculationpart 15, a predicted energy charge calculation part 16, a publictransportation charge calculation part 17, a total charge calculationpart 18, and a moving route selection information provision part 19.Hereinafter, processing in the case that the user Pu uses the rentalvehicle 100 provided by car sharing will be described.

When user information transmitted from the user terminal 120 accordingto a registration operation by the user Pu is received, the usermanagement part 11 records the information of the profile of the user Puincluded in the user information and the user ID issued to the user Puor the like in the user management information 32. In addition, whenreservation information of the rental vehicle 100 including the vehiclereservation No. is received from the user terminal 120, the usermanagement part 11 transmits a reservation content request Csi_rqrequesting transmission of reservation content information Csiindicating reservation content of the rental vehicle 100 to the vehiclemanagement server 200.

The vehicle management server 200 which receives the reservation contentrequest Csi_rq refers to the vehicle management information 201, andtransmits the reservation content information Csi of the rental vehicle100 to the vehicle utilization support system 1. The user managementpart 11 recognizes the reservation content of the rental vehicle 100 bythe user Pu by the reservation content information Csi, and records thereservation content in the user management information 32. Thereservation content includes the reservation period and the scheduledreturn spot of the rental vehicle 100.

The in-vehicle device 110 loaded on the rental vehicle 100 has afunction of detecting the current position of the rental vehicle 100 bya GPS (Global Positioning System) sensor and a function of guiding aroute to a destination. The in-vehicle device 110 guides the route bydisplaying a map indicating the moving route on a display 111 andoutputting guidance by voice from a speaker 112.

The moving route extraction part 12 recognizes the current position ofthe rental vehicle 100 by receiving current position information of therental vehicle 100 transmitted from the in-vehicle device 110 of therental vehicle 100. In addition, the moving route extraction part 12refers to the reservation content of the rental vehicle 100 recorded inthe user management information 32, and recognizes the scheduled returnspot of the rental vehicle 100. Then, the moving route extraction part12 refers to the map information 33 and extracts a moving route Rt fromthe first spot Mp1 which is the current position of the rental vehicle100 to the second spot Mp2 which is the scheduled return spot.

In the case where the moving route Rt extracted by the moving routeextraction part 12 includes a traveling section of a toll road such as ahighway, the travel charge calculation part 13 calculates the travelcharge on the moving route Rt on a basis of the map information 33 orthe road information received from a traffic information server (notshown) or the like.

The predicted moving time calculation part 14 calculates the predictedmoving time by the moving route Rt on the basis of a traveling distanceand an assumed traveling speed for the traveling section by the rentalvehicle 100, and calculates the predicted moving time by referring tothe public transportation information 34 for the moving sectionutilizing the public transportation. Here, the assumed traveling speedof the rental vehicle 100 is set at 100 km/hour on the highway and 40km/hour on the general road for example. The predicted excess chargecalculation part 15 calculates a predicted excess charge when it isassumed that the reservation period of the rental vehicle 100 elapseswhile the user Pu is in the middle of moving on the moving route Rt bythe rental vehicle 100.

The predicted energy charge calculation part 16 calculates the predictedenergy charge which is a charge of energy predicted to be consumed bythe rental vehicle 100 when moving on the moving route Rt using therental vehicle 100, according to a model of the rental vehicle 100.Specifically, the predicted energy charge calculation part 16 calculatesenergy consumption of the rental vehicle 100 on the moving route Rt bydividing the traveling distance of the rental vehicle 100 by energyconsumption per unit distance of the rental vehicle 100 set according tothe model of the rental vehicle 100 and a kind (the highway or thegeneral road) of a traveling road.

Then, the predicted energy charge calculation part 16 calculates thepredicted energy charge of the rental vehicle on the moving route Rt bymultiplying the energy consumption of the rental vehicle 100 on themoving route Rt by an energy charge per unit amount. For example, whenthe rental vehicle 100 is a vehicle that uses fossil fuel such asgasoline, the charge of the fossil fuel to be consumed is the predictedenergy charge. In addition, when the rental vehicle 100 is anelectrically driven vehicle, the charge of electric power to be consumedis the predicted energy charge. The public transportation chargecalculation part 17 calculates a utilization charge of the publictransportation to be required when the moving route Rt includes themoving section utilizing the public transportation.

The total charge calculation part 18 calculates a total charge which isa total of the travel charge calculated by the travel charge calculationpart 13, the predicted excess charge calculated by the predicted excesscharge calculation part 15, the predicted energy charge calculated bythe predicted energy charge calculation part 16, and the utilizationcharge of the public transportation calculated by the publictransportation charge calculation part 17.

In the case where the plurality of moving routes Rt are extracted by themoving route extraction part 12, the moving route selection informationprovision part 19 provides moving route selection information regardingselection of the moving route.

2. First Embodiment of Moving Route Selection Information ProvisionProcessing

According to a flowchart shown in FIG. 5, a first embodiment ofprovision processing of moving route selection information executed bythe vehicle utilization support system 1 will be described.

When the registration operation for receiving the support service by thevehicle utilization support system 1 is performed by the user Pu of therental vehicle 100, in step S20, the user terminal 120 transmits userinformation Usi and reservation information Rnti of the rental vehicle100 inputted by the registration operation to the vehicle utilizationsupport system 1. The user information Usi includes the profile of theuser Pu or the like, and the reservation information Rnti includes thevehicle reservation No. issued when the user Pu reserves the rentalvehicle 100.

In step S1, the user management part 11 of the vehicle utilizationsupport system 1 receives the user information Usi and the reservationinformation Rnti. Then, the user management part 11 issues the user IDby performing registration processing of the user Pu, and records theprofile and the user ID of the user Pu in the user managementinformation 32. In addition, the user management part 11 transmits thereservation content request Csi_rq including the vehicle reservation No.to the vehicle management server 200. Then, the user management part 11recognizes the reservation content of the rental vehicle 100 by the userPu by receiving the reservation content information Csi transmitted fromthe vehicle management server 200, and records the information of thereservation period and the scheduled return spot of the rental vehicle100 in the user management information 32.

In step S21, the user terminal 120 transmits use start information ofthe rental vehicle 100 to the vehicle utilization support system 1according to a use start operation of the rental vehicle 100 by the userPu. In step S2, the moving route extraction part 12 of the vehicleutilization support system 1 receives use start information Cust of therental vehicle 100 from the user terminal 120, and also receives vehicleinformation Cinf from the rental vehicle 100.

Then, the moving route selection information provision part 19 recordsmovement information including the travel charge, the predicted requiredtime, the predicted excess charge, the predicted energy charge, thepublic transportation charge, and the total charge that are calculatedfor the individual moving route Rt in the moving route information 35for each moving route Rt. In an example shown in FIG. 1, the firstmoving route Rt1, the second moving route Rt2 and the third moving routeRt3 are extracted by the moving route extraction part 12, and as shownin FIG. 4, the movement information of the first moving route Rt1, thesecond moving route Rt2 and the third moving route Rt3 is recorded inthe moving route information 35.

In subsequent step S4, the moving route selection information provisionpart 19 transmits movement condition Mcnd indicating movement conditionsof the individual moving routes Rt to the user terminal 120. In thiscase, the movement condition Mcnd may include the travel charge, thepredicted required time, the predicted excess charge, the predictedenergy charge, the public transportation charge, and the total chargeshown in FIG. 4, and may include only the predicted required time andthe total charge for example. The movement condition Mcnd corresponds tomovement condition comparison information which enables comparison ofthe total charge and the predicted moving time of each moving route ofthe present invention.

In step S22, the user terminal 120 receives the movement conditions ofthe individual moving routes Rt, and displays a moving route selectionscreen at a display part (not shown). On the selection screen, paths ofthe individual moving routes Rt1, Rt2 and Rt3 shown in FIG. 1 and themovement conditions of the individual moving routes shown in FIG. 4 arelisted and displayed, and the user Pu can confirm the selection screenand select any desired moving route.

In next step S23, when a moving route selecting operation is performedby the user Pu, the user terminal 120 advances processing to step S24,and transmits selection result information Seli indicating a selectionresult to the vehicle utilization support system 1. When the selectionresult information Seli is received from the user terminal 120 in stepS5, the moving route selection information provision part 19 of thevehicle utilization support system 1 transmits selected moving routeinformation Srti indicating the selected moving route to the rentalvehicle 100.

In step S51, the in-vehicle device 110 of the rental vehicle 100receives the selected moving route information Srti from the vehicleutilization support system 1, and executes route guiding according tothe moving route indicated by the selected moving route informationSrti. The in-vehicle device 110 guides the route by displaying the mapindicating the moving route on the display 111 and outputting theguidance by voice from the speaker 112.
